APPARATUS FOR MAKING GAS.

SPECIFICATION formingpart of Letters Patent No. 270,427, dated January 9, 1883.

Application filed July 14. 1882. (N model.)

T 0 all whom t't may concern Be itlrnown that I, JOHN HANLON, of the city and county of New York and State of New York, have invented a new and Improved Apparatus for Making Gas; and I hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, makiugpart of this specification, in which- Figure 1 is an elevation of a double bench of retorts, the fronts of one bench being removed. Fig. 2 is aside elevation of the apparatus, with a portion of the masonry removed to show the tire-box. Fig. 3 is a longitudinal Fig. 4=lS alongitudinal section through superheater and steamretort. Fig. 5 is a vertical section near the front of retorts. Fig. 6 is a front view of super-heater; Fig. 7, cross-sectionalview of Woodretort.

My invention relates to that class of apparatus designed to utilize wood in the manufacture of heating or illuminating gas; and my invention consistsin certain combinations and arrangements of devices whereby the gas is readily and economically produced, as will hereinafter be fully described and specifically claimed.

In order that those skilled in the art may make and use my invention, I will proceed to describe the manner in which I have carried it out.

In the saiddrawings, A is a superlieatingchamber, centrally located in the masonry above the tire-place or furnace B. On each side of thesuperheater and furnaceare benches of retorts O U, divided longitudinally by iron plates a a, for a purpose hereinafter set out. At their forward ends the retorts O C are connected by the short pipe I), and the retorts G U are connected in like manner by short pipe I). The iron plates at a have openings 1) b at the rear ends of the retorts. The superheating-chamber is made with a series of shelves, d d, provided with openings e e at alternate ends, forming zigzag fluesfand at the top ofthe chamber steam is introduced through a pipe, E, the end section of which is provided with perforations, and is covered and shielded from the intense heat of the oven by means of perforated plate F. A steam-gage is located on pipe E, and steam is admitted at the same pressure with that of the gasholder, thus arrows.

[avoiding any back-pressure in the retorts.

After the steam is super-heated it leaves the superheater by pipe G, which taps a crosspipe, H,'connecting the lower portions of the retorts G O, and by means of cocks ff the steam can be directed to either of the retorts or to both. The gas passes from the retorts through pipes I into the hydraulic main K.

If desirable, pipes P I may conduct into pipe H, at its ends, a hydrocarbon oil to enrich the gas for illuminating purposes.

The space between the iron plates a (t and the bottoms of the retorts I till with coke and wrought-iron scraps, for a purpose hereinafter described.

The retorts 0 above the platesaa are charged witlmvood, and after the wood-gas is generated by the application of sufticient heat, steam is admitted into the snperheater Aand is conveyed through it, as is indicated in Fig. 4 by The superheated steam enters retorts O by pipe G, retorts 0 being cut off by cock f, and, passing through the body of coke and scrap-iron in thelower retort, oxidiz s the iron, while its hydrogen is set free, andthis, passing through the main body of the retort, as indicated by the arrows, seizes the carbon remaining in the wood-holding portion of the retort to form the gas which passes through short pipe D to the upper retort in the same manner, and out of pipes I into the hydraulic main K, whence it is conducted to the points lower portion provided with a mass of coke and iron scraps mixed, a retort-chamber, a fire-box, B, a superheating-chamber, A, containing a perforated steam-supply pipe surrounded bya perforated shield-plate, F, steampipes E and G, and oil-pipes P P, substantially as and for the purpose set forth.

JOHN HANLON.
